Version 3.1.3 of Hemi is out.
The source and source+builder archives are available on the Google Code project page.
Version 3.1.3 includes additional updates to the Module Service, Test Module, and in-page unit testing with the testableApplication Component.
The Get Started with Hemi and Unit Testing article introduces using the testable component for writing in-page node-specific unit tests.
More updates were made to the Data IO layer, and the Distributed Web Application Component templates were migrated from being tightly bound to the Core Web project to use the Data IO layer with the Core Web interface abstracted out as a provider.
This allows the static Hemi components, templates, and fragments to be accessible via the designer and the Framework IO Provider.
You can Try the Framework Designer to explore the Hemi project.
